- for automobile bodies, and has for the primary object the provision of a device of this character which will permit delivery into the body of the automobile 'while standing .or running atmospheric air and at'the same time remove air from the body so that the airwithin thebody will be kept free of any deadly fumes ,or gases and from becoming stagnant and unhealthy for the occupants and which allows for the safe operation of the automobile with all windows closed to exclude rain, snow and the like.

With these and other objects in view, the invention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a diagrammatical view showing an automobile body equipped with a ventilatingdevice constructed in accordance vention.

Figure 2 is a longitudinal sectional view showing the automobile body with the air exchange pipes located therein. v

Figure 3 is a fragmentary vertical sectional view showing the air inlet means as being mounted. on the top of the body, and taken on line 3-3 of Figure 1.

Figure 4 is a view similar to Figure 3 showing the air outlet means, and taken on the line 4-4 of Figure 1.

Figure 5 is a diagrammatical view illustrating the wiring diagram and a fragmentary portion of the engine of the automobile and a governor driven thereby for the automatic actuation of the control switch of the circuit.

Referring in detail to the drawings, the numeral 5 indicates an automobile body of a conventional construction. The roof 8 thereof has mounted thereon and extending to the interior of the body ventilating casings l and 8. The ventilating casing I faces'forwardly of the automobile body, that is, the opening thereof faces the direction in which the automobile travels while the casing l is reversely positioned, that is, the opening thereof faces rearwardly of the direction of travel of the automobile. The openings of the casings I and 8 have arranged therein louvers 9 to prevent rain, snow or the like from beating into the casings. Each casing includes a necli II) which extends through the roof of the body and also an attaching flange II secured with my inon the. roof in any well known mannerto effect a seal between the casing and the roof. v

-An air inlet pipe I2 is connected to the neck of the casing I and extends downwardly in the automobile ,:body and horizontally over the floor '6 thereof withthe horizontal portion provided with a series of perforations for'the purpose of eifectively delivering atmospheric air into the body adjacent the floor. The. neck In of the casing 8 has connected thereto an outlet pipe I3 which is arranged in the body adjacent the roof and is provided with a series of perforations. The purpose of the outlet pipe is to convey air from the body outwardly thereof by way of the casing 8.

Electric motors I4 are mounted in the casings l and 8 and the shafts thereof have secured there-' on fans I5. The electric motors I4 are connected in an electric circuit I6 and the source of electrical energy for the circuit is indicated by the character I! and may be the storage battery of the automobile employed for the illumination of the lights of the automobile. The circuit Itincludes a resistant type switch I8 operated by a governor I9 and the latter has a. drive connection to the engine of the automobile. The engine is indicated by the character 20 and the drive of the governor by the character 2|.

When the automobile is standing idle or the engine operating at a very slow rate of speed, the governor I9 acts to close the switch I8 of the circult I6 so as to bring about energization ofthe motors I4 for driving the fans I5. The fan in the casing 1 draws air therein and forces said air into the body by way of the air inlet pipe I2, while the fan I5 of the casing 8 creates a suction therein drawing the air out of the body by way of the air outlet pipe I3. This brings about an efficient ventilation of the automobile body while the'automobile is standing still or operating at a very slow rate of speed. However, as the speed of the automobile increases above a predetermined speed, the governor I9 acts to open the switch and break the electric circuit to stop the operation of the motors I 4. The automobile operating at this rate of speed is sumcient to bring about circulation of air through the body by way of the casing I and the air inlet pipe I2 and to draw air out of the body by way of the air outlet pipe'IS and'the casing 8. Through the arrangement of the governor and switch I8 it will be seen that the automobile body will be efliciently ventilated either when the automobile is standing idle or operating at a very slow speed or when operating at a high rate of speed and sufilcient to bring about a ciiculation of air through the casingsl and 8 due to the forward travel of the vehicle. With this arrangement electricity will be conserved as it is only utilized when the automobile is standing idle or operating at a very slow rate of speed. 7

Also located inthe circuit I6 is a manually actuated switch 22 for opening and closing the circuit I 6 and for permitting operation of the motors H at different speeds. This switch is preferably located in convenient reach of the operator of'the automobile. It will be seen through the use of the switch 22 the motors may be rendered inoperative when the automobile is left unattended. I I j Through the employment of the ventilating device shown in the drawings and herein de-i scribed in detail will permit an eiiflcientventilation of the automobile body so that the occupants thereof may be, rendered comfortableiandsafe from inhaling dangerous and obnoxious fumes which may enter the automobile body' from the engine of the automobile and also prevent the air from becoming stagnant and unhealthyand allows for the safe operation of the automobile with all of the windows in a closedposition so that weather elements will be excluded, consequently adding to the comfort of the occupant.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those s led in the-art to which such a device relates, 'softhat further detailed description will not be required.

WhatIclaimis:

In combinationwith an automobileincluding an engine and a body, casings mounted on the exterior of the body and each having an open side and said casingshaving the open sides thereof reversely arranged'tojeach' other, an air inlet pipe connected to one of said casings and ex,- .tending intothebody, an air outlet pipe connected to the other casing and arranged on the ine terior of the body, electricmotors mounted in said casings, fans operated by said motors, an; electric circuit connected to said motors and in-{ cluding a manually controlled switch and an electrical source, and a governor actuated switch ofthe resistant type for operating the fans at variable speeds and for, stopping said fans, a

govemor' whereby said overnor in combination engine and to' stop said fans when said en ine is 25 operating faster than a'predeterminedspe d opcrating the governor type switch, an'd'a drive means between the engine and the governor.
